About VioGraph

Graph analytics, finally built for the data warehouse era.

We're building what we wish existed when we were data engineers: a graph layer that plugs into Snowflake or BigQuery in minutes, costs nothing when idle, and makes multi-hop analysis feel as routine as writing SQL.

Our story

VioGraph is a product by Vioah Ltd, a London-based engineering studio. The company was founded by a DevOps engineer who watched analyst after analyst hit a wall: “Can I see everything connected to this customer?” And every time, the answer was the same seven JOINs, two CTEs, and thirty minutes of waiting.

Graph databases solve this — but every existing option requires copying data out of the warehouse, running a 24/7 cluster, and training analysts in a new system. For most enterprises that's a non-starter. So we built the alternative: a graph engine that reads directly from the warehouse, spins up only when queried, and shuts down when done.

We're early — but the product is live, open source, and used by teams doing fraud investigation, infrastructure impact analysis, and customer-360 analytics today.

What we believe

Warehouse-native, not warehouse-replacing

Your data stays in Snowflake, BigQuery, Databricks, or Starburst. We don't ingest it, copy it, or ask you to pay twice for storage.

Zero idle cost — or it isn't serverless

Every competitor says "serverless." Most still charge you when nothing's running. We spin compute up per query, and tear it down after.

Analysts first — not just engineers

Graph databases have been engineer-only for twenty years. VioGraph is a product: dashboard, AI queries, shareable views — so the whole data team can use it.

Where we are

London, United Kingdom

We're a small remote-first team shipping VioGraph from the UK. If you're a bank, insurer, or data-intensive enterprise exploring graph — or a practitioner who wants to help shape the product — we'd love to hear from you.
